Clue 5
Division facts (1-12) — the last clue
Let's divide our team of young geographers equally among the search zones to decode the final clue.
First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!
Step 1 — solve these
9 ÷ 9 = ?
25 ÷ 5 = ?
80 ÷ 8 = ?
33 ÷ 11 = ?
6 ÷ 3 = ?
48 ÷ 4 = ?
8 ÷ 1 = ?
22 ÷ 2 = ?
32 ÷ 8 = ?
42 ÷ 7 = ?
77 ÷ 11 = ?
Step 2 — cross out the sentence with each answer
1.The villain uses compass magnetism to spin the coordinates, then hides away using jungle blending.
2.The villain uses compass magnetism to spin the coordinates, then soars high with altitude flight.
3.The villain uses compass magnetism to spin the coordinates, then escapes with deep sea diving gear.
4.The villain summons a tiny backyard volcano, then digs deep using cave tunneling.
5.The villain freezes the rivers into mini glaciers, then hides away using jungle blending.
6.The villain blows desert sandstorms over the plains, then hides away using jungle blending.
7.The villain freezes the rivers into mini glaciers, then tracks targets with space satellites.
8.The villain blows desert sandstorms over the plains, then escapes with deep sea diving gear.
9.The villain shifts tectonic plates to make hills, then hides away using jungle blending.
10.The villain shifts tectonic plates to make hills, then digs deep using cave tunneling.
11.The villain shifts tectonic plates to make hills, then tracks targets with space satellites.
12.The villain blows desert sandstorms over the plains, then soars high with altitude flight.
